Locking/Unlocking Header Float

Two header float locks—one on each side of the float module—lock and unlock the header float system.
IMPORTANT:
The float locks must be engaged when the header is being transported with the float module attached so there is no
relative movement between the float module and the header. The float locks also must be locked when detaching
from the combine to enable the feeder house to release the float module.
